Please note that noise will happen in these situation:
(1)Hardware problem:
-Power supply is not sufficient or not stable;
-Using switch power supply
-Using transformer as power supply and without shield & isolation; wdo not avoid interference
-Local at the environment with electromagnetic interference
-Audio input has its own problem
(2)Software problem:
-Audio driver setting
-Music Player effects setting

Solution:
(1)Hardware problem-> The power supply should not be placed too close to the amplifier board in order to avoid electromagnetic interference. It is better to use high quality power supply which offers stable power. If you use power transformer, using an iron sheet to cover the transformer is highly recommended.
(2)Software problem-> When you connect the amplifier to telephone or computer, you can turn off the special effects software or sound card driver effects settings. Using the software after making sure they will not take effect on the sound effect.

Input voltage: DC 12-24V
Storage mode: Support TF card & U disk
Output power: 50W*2
Channel amount: two
Transmission distance: about 20m
Product size: 73x68x16mm(length x width x height)

Equipment:
-4-key: MODE(bluetooth/ U disl/TF card switching); PLAY(play/stop); PREV/V-(“short press” to previous song; “long press” to decrease volume); NEXT/V+(“short press” to next song; “long press” to increase volume)
-Indicators: with power indicator & bluetooth indicator
-USB port
-TF card
-Terminals: for connecting power supply and right/left speakers

How does the amplifier work:
-When the amplifier is on powering status, GREEN light goes first and then BLUE light;
-After connecting bluetooth/ U disk/ TF card, the BLUE light flashes, which means that the amplifier is on working status;
-When amplifier is on powering status,GREEN light appear and accompanied by BLUE light flashing. Default mode is “bluetooth”. Switch on the bluetooth function on your mobile phone or car, searching “Bluetooth” and there will be a voice prompt after connecting or disconnecting, bluetooth will be preferentially chosen at this time. There is also a voice prompt and the USB or TF card will be preferentially chosen when connecting them.
-Under Bluetooth Mode: Blue/Green lights flash alternately(searching equipment); Blue light keeps lighting on(successfully connect the bluetooth)

Note:
Please figure out the Positive+ and Negative- before wiring the amplifier;
Input voltage can not be too low or exceed 24V

Precaution:
1. NOT include a power supply, please prepare a DC 24V 5A 120W power supply with 5.5*2.1mm barrel connector;
2. Do not use power transformer to power on this amplifier! (Because power transformer uses AC electricity, this amplifier only applies to DC electricity);
3. Do not connect the amplifier in series or parallel arbitrarily to get higher output power;
4. It is a normal phenomenon that there is rustle coming from the amplifier even if no sound is played. Well connect the audio wire and MP3, there won’t have noise when playing music and please turn off the amplifier if you do not play music.
